How about adding an option to the AAC Encoder utility to create files with a .m4a file extension instead of .mp4 (for all the iTunes and iPod users out there) to avoid having to manually rename files or having to run an extra program/script to rename file extension fom .mp4 to .m4a? Thanks.

foobar's CLI can specify the output extension. Or you can use something like ezXTN--a nifty little batch extension converter (just Google it) with drag-and-drop capabilities.
